I'd go for a GPS receiver capable of outputting carrier phase data. You'll 
have to log more data (you'll have a laptop, disk space won't be a problem). 
But this way, you can use differential post-processing (RINEX et al).

In plain english, this means that you'll get sub-metric accuracy, which kinda 
rocks.

You'll have to do a bit of research, and you'll have to avoid consumer-grade 
receivers, but I do think that sub-metric accuracy is worth it.


Cheers,
